Which organization maintains standards to ensure medication quality and uniform potency in the United States?

• A. National Formulary (NF)
• B. United States Pharmacopeia (USP)
• C. On-line medical control
• D. Parenteral medications

Answer: (B)

The United States Pharmacopeia (USP) is the organization that sets and maintains the official standards for drug quality in the United States. USP develops monographs and general chapters that define how drugs should be identified, tested, and labeled to ensure identity, strength, quality, and purity across all lots. The FDA recognizes USP standards as official benchmarks, and the combined publication of USP and the National Formulary (USP–NF) serves as the official reference for medicinal products. This framework ensures medications have uniform potency and meeting safety criteria nationwide.

Other options don’t fit this role: online medical control relates to EMS medical direction, not standard-setting for medications; parenteral medications describe a route of administration rather than an organization responsible for standards; the National Formulary exists as part of the compendium but the standards are maintained by USP (with NF now integrated into USP–NF).
